The 6,800 square meter, 5-story, low-energy facility has 70 km of storage shelves and was designed to integrate into the landscape while meeting EDF’s stringent environmental standards. The interior of the archives is humidity controlled and fire resistant. Shiny steel studs are embedded into the earth-colored concrete facade as a way of blurring the building’s boundaries and reflecting the color of the changing seasons. Perforated screens cover entrances and patios to provide shade to the interior of the building. Meanwhile, two layers of concrete (structure and facade) plus 30 cm-thick walls provide high-performance insulation to reduce cooling loads inside.
There is no on-site connection to sewage at the facility’s countryside location, so a low-cost natural wastewater system was installed to treat sewage, greywater, and rainwater. Completely integrated into the landscape, the wastewater system efficiently eliminates nitrogen (70%), phosphorus (60%) and pathogens. A double-flow ventilation system with heat recuperation as well as energy-efficient lighting and a heat pump system further reduce energy usage down to 29 kWh/sq m. Renewable energy systems (of an undisclosed nature) supply power back to the building.
